My new boat delivers in two weeks and I have ordered (to be installed myself) Furuno Navnet TZtouch2 12.1 and the Furuno Drs4d-Nxt radar. The boat is a Kingfisher 26ft pilot house and is an aluminum boat so I will not be using a thru hull transducer. It has welded on transducer pads for mounting the transducer so what is the best transom mount transducer I can buy to use here? I want make sure I can use the Rezboost and bottom discrimination functions but am unsure as to EXACTLY which TM transducer to buy to make sure this is possible. Thank you in a advance for your time regarding this silly question but I thought it better to come here and ask this of you guys who actually know rather than some other board where the information could prove to be incorrect..
